Hi,

I'm just looking for some advice whether the stats attached are OK to move from ADSL to VDSL.

Thanks for any guidance.

Then old role of thumb was 10.8dB attenuation on the downstream was the install limit, but there's been a number of installs here well over that recently

Your sync rates look pretty good for the attenuation which suggests a low noise line so it's probably worth a try

Your stats are not dissimilar to mine in this thread, and I'm getting OK VDSL2 speeds

Ignore your attenuation figure in the modem, it means nothing. The 10.8 figure is done at a different frequency and will differ to what your modem says.
A rule of thumb, if you are on Chorus gear and get 16Mbps or higher on ADSL2+, then good probability you can get VDSL. 14-15Mbps, you are at the lower end and may or may not get VDSL. Less than 14Mbps and you are unlikely to get VDSL unless you currently don't have a master filter and your home wiring is very bad, which means the VDSL install will fix this :)
